Night Agent: night agent Season 3 Cast — Every Character, New and Returning

night agent returns with Gabriel Basso’s Peter Sutherland facing higher stakes: a young Treasury agent has fled to Istanbul with sensitive government intel, setting off a cross-border chase that pits Peter against assassins, dark money and a relentless journalist. The season promises "new thrills, new worlds, new stunts, new characters, and new adventures. "

Night Agent: Season setup

Shawn Ryan’s The Night Agent premiered in 2023 and quickly became one of the platform’s most-watched series of all time. Season 1 combined high-octane action with sharp political intrigue and introduced the high-pressure world of Night Action, anchored by Gabriel Basso’s grounded performance as Peter Sutherland. Season 2 expanded that world, pulling Peter out of the White House and sending him across the globe while introducing new characters, international threats and a more tangled political conspiracy. Critics and reviewers note that Season 2 sometimes felt overpacked, with the plot growing convoluted and the emotional throughline occasionally getting lost; Season 3 is presented as a return to the show’s roots, a tighter, more focused season that many see as the strongest the series has produced so far.

Peter Sutherland’s Istanbul manhunt

Off the heels of Season 2, Peter is still operating as a double agent and waiting for a call from intelligence broker Jacob Monroe (Louis Herthum) when he accepts what appears to be a straightforward mission: track down FinCEN employee Jay Batra (Suraj Sharma), a man accused of murdering his boss after uncovering sensitive government intel. That Treasury/FinCEN lead has fled to Istanbul, and when Peter locates Jay there it becomes clear nothing is simple. What begins as a manhunt spirals into a sprawling investigation involving dark money, political influence and paid assassins determined to eliminate anyone who gets too close. Peter teams up with relentless journalist Isabel De Leon (Genesis Rodriguez) as the conspiracy he chases turns out to hit much closer to home.

White House tensions and Hagen

Back in Washington, Season 1 fan favorite Chelsea Arrington (Fola Evans-Akingbola) is once again stationed inside the White House, now serving in the Secret Service detail for President Richard Hagen (Ward Horton) and First Lady Jenny Hagen (Jennifer Morrison). After saving the day in the first season, Agent Chelsea Arrington is now the First Family’s top Secret Service officer. Chelsea is the first to sense that something isn’t adding up; her instincts point toward tensions and secrets within the administration that don’t align with the public image being projected. Hagen’s presidency is already shadowed by the election manipulation revealed in Season 2, and that history informs the stakes of the current season as questions of legacy and betrayal surface for President Richard Hagan, who enjoys bipartisan popularity and is aiming for a lasting legacy but faces tough choices and betrayals that force him to decide whether he wants to be remembered as a great president or a good man.

Cast additions and returning faces

Peter Sutherland (Gabriel Basso) returns haunted by his choices from Season 2 and back on the hunt for a mysterious broker; catching him comes at a cost. Joining him this season are Genesis Rodriguez and David Lyons, with Lyons becoming Peter’s new partner though he’s not entirely sure he can trust him. Jacob Monroe, Peter’s nemesis and the broker, used to seem untouchable; this season gives a closer look at Jacob Monroe and the human side behind the villain. Other recurring and new characters include: Aidan Mosley / Aiden Mosley — the context lists both spellings — described as FBI Deputy Director Aiden Mosley, a principled, no-nonsense leader with decades of experience who is one of the few who knows Peter’s secret about the broker and who does his best to back him; Catherine Waver, the sharp, no-nonsense operator who pulled Peter out of trouble and gave him a shot at redemption and who is determined to finally take down the elusive broker; and Chelsea Arrington in her Secret Service role.

The season’s cast credits are noted in the available material: Gabriel Basso is said to be best known for his breakout role in Super 8, in which he played J. J. Abrams, and his other credits are listed as A House of Dynamite, The King of Summers, Hillbilly Elegy, The Big C and Trigger Warning. Fola Evans-Akingbola’s credits include Siren (where she played marine biologist Maddie Bishop), Ten Percent (as Zoe Spencer), an episode of Black Mirror, Game of Thrones, the film Back in Action and the crime series Death in Paradise.

Amanda Warren’s credits include The Purge, The Leftovers, Dickinson, East New York and Gossip Girl. Genesis Rodriguez and David Lyons are named as season additions in the cast list.

Series arc, Rose and final notes

Going into Season 3, the absence of Luciane Buchanan’s Rose was a notable talking point: Rose was central to Season 1 but, by the end of Season 2, the creative decision was made to let that relationship rest. The context says that what bonded Peter and Rose was trauma and survival, not a sustainable future, and that Season 3 keeps Rose as Peter’s moral compass while her absence prevents cheapening her impact. The review material ends mid-sentence with the fragment "This shake-up in the cast also makes roo" — unclear in the provided context.

Season 3 of night agent promises a condensed, character-driven arc that reunites returning leads, introduces new partners and pushes Peter Sutherland into a personal and political confrontation that spans Istanbul and the White House.
